It had been a day since I sent Amelia to that bar, and she returned with some information yesterday.
However, none of the information she provided was directly related to my case.
She simply mentioned that she had hired an information broker among a few other things.
According to her, it would take around a day for her trusted information broker to investigate my case.
I had no idea how Amelia had managed to contact an information broker, but if she trusted them, maybe I could too... though I couldn't help but doubt that this broker was as skilled as Shadow Rose.
Shadow Rose was a character in the novel and had been an invaluable helper for Nero and his group in the later parts of the story when the war arc started.
Regrettably, I had no clue where to find Shadow Rose at this point in the story, or else solving these mysteries could've been so much easier.
